FIRST YEAR SINCE 1903 WITH NO WORLD SERIES

Baseball owners proposed a new plan to share broadcast revenues — in hopes of helping teams in smaller markets — but also insisted on a salary cap.

Players, distrustful after a series of anti-collusion rulings by arbitrators that resulted in a $280 million settlement, rejected the salary cap and the elimination of arbitration.

Months of talks resulted in no movement by either side. On Aug. 12, 1994, the players walked out.

Acting commissioner Bud Selig canceled the remainder of the season on Sept. 14, including the playoffs and World Series. It was the first year since 1903 with no World Series.

By January 1995, Congress had proposed laws ordering an end to the strike. Owners moved to break the strike by hiring replacement players.

With Opening Day looming, the players’ union agreed to return to work if the courts supported an unfair labor practices complaint against the owners. U.S. District Court judge Sonia Sotomayor — who would later be named to the Supreme Court — ruled against the owners on March 31.

The 1995 season opened three weeks behind schedule, 25 years ago Saturday. Teams lost about $1 billion in revenue and MLB attendance would suffer for much of the next decade.
